nice that made this future project much easier. have edit also. i figure i will go this rought because it will be cheaper in the long run. but the tranny is my next step. so lets talk about converters for the 80. do they have any thing like the yank tt3000?

 

I might be able to try it out pritty soon. My truck is just sitting in my shop right now with a blown tranny. 4l80E is my next step if i can gather enough money. It is hard to find extra money when starting a new business. So it might take a while. Hopefully not.

 

Yes their is a yank 2600 and 3200 converters for the 4L80e. The only downside to this heavy duty trans is its a hydramatic 400 with an overdrive gear, so its first gear is 2.48 unlike the 4L60e with a 2.75(or so?) 1st gear. But I have felt no ill affect of it infact my 60foot time corelates to a faster ET.

 

You can use the taller 1st and 2nd gear to your advantage by adding a lower final drive ratio with the shorter 4th it's like having a close ratio gear box.Most Turbo 400 performance parts will work to including a low gear planetary gear set with a 2.75 first gear.Best of all the L480e can stand up to a WOT 4th gear shift.
